CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application No. 63/180,551, filed Apr. 27, 2021, which is incorporated by reference in its entirety herein.

TECHNICAL FIELD

The present disclosure is generally related to cameras that feed or stream an image or video in real time.

BACKGROUND

Webcams can be built into laptops to feed or stream an image or video in real time to or through a computer network, such as the Internet. However, webcams are typically not built into flatscreen monitors that are attached to docking stations or laptops. Such flatscreen monitors can therefore need the additional expense of a separate webcam. Moreover, the maximum resolution of webcams is lower than most smartphones or tablets, and webcams can malfunction when the correct driver is not installed on a host computer.

FIG. 1 is a drawing illustrating an example electronic device to be operated as a web camera, in accordance with one or more embodiments. In embodiments, a case 100 is used for housing a mobile device and operating the mobile device as a webcam. A webcam is a video camera that feeds or streams an image or video in real time to or through a computer network, such as the Internet. Webcams are typically small cameras that sit on a desk, attach to a user's monitor, or are built into the hardware. Webcams can be used during a video chat session involving two or more people, with conversations that include live audio and video.

The case 100 includes a housing 110 made of at least one of rubber, plastic, leather, or silicone. The housing 110 is configured to house (e.g., encase, hold, enclose, etc.) a mobile device. The mobile device can be a smartphone, a tablet, a fitness tracker, or a smartwatch. In embodiments, the mobile device has a first camera 108 disposed on a first side (the side shown in FIG. 1 ) of the mobile device. In embodiments, the mobile device has a second camera disposed on a second side of the mobile device opposite to the first side. An example second camera 524 on an example second side 528 of an example mobile device 504 is illustrated and described in more detail with reference to FIG. 5 . Likewise, embodiments of the case 100 can include different and/or additional components or can be connected in different ways.

For example, the case 100 can include the protective housing 110 that holds a smartphone or other handheld device and protects the device against physical damage. The protective housing 110 can be substantially made of plastic, rubber, silicone, leather, etc. The protective housing 110 can enclose four sides of a smartphone. In addition, the protective housing 110 can cover the rear side of the device as shown by FIG. 1 . A portion of the housing 110 overlaying a rear camera 108 of the mobile device can be transparent or the protective housing 110 can define an opening 102 that exposes the rear camera 108.

In embodiments, the housing 110 is shaped to expose the first camera 108 and the second camera for capturing images when the mobile device is housed by the housing 110. For example, the housing 110 can define an opening 102 overlaying the camera 108 to expose a lens of the camera 108 when the mobile device is housed by the housing 110. In another example, the housing 110 includes a transparent portion configured to overlay the camera 108 to expose a lens of the camera 108 when the mobile device is housed by the housing 110. In embodiments, a fastener 104 is attached to the housing. The fastener 104 is configured to attach the case 100 to a frame of an electronic display in a first configuration as shown by FIG. 2 . An example frame 204 of an example electronic display is shown in FIG. 2 .

In embodiments, a magnet 106 is disposed (e.g., embedded) within or attached to the housing 110. The magnet 106 is configured to trigger a sensor disposed within the electronic display or a computer communicably coupled to the electronic display. An example sensor 220 and example computer 208 are shown by FIG. 2 .

FIG. 2 is a drawing illustrating an example of operating an electronic device as a web camera, in accordance with one or more embodiments. In embodiments, a housing 200 of the electronic device is attached to a fastener that attaches the housing 200 to a frame 204 or a housing of an electronic display 228. An example fastener 104 is shown by FIG. 1 . The electronic display 228 can be a laptop's screen as shown by FIG. 2 , or a flatscreen monitor as shown by FIG. 5 . In a first configuration, a camera of the electronic device faces a user facing a screen of the electronic display 228. Likewise, embodiments of the system can include different and/or additional components or can be connected in different ways.

The housing 200 can include a fastener and a magnet. The fastener can be configured to attach the housing to a display 228, such as a laptop monitor or television. In embodiments, the fastener includes at least one of an adjustable clamp, a clip, a strap, an adhesive strip, or a foldable element. The fastener can be a clip, strap, adhesive, foldable element, or other suitable mechanism to attach the housing 200 to the electronic display 228. In embodiments, the fastener is configured to attach the housing 200 to a frame 204 of an electronic display 228 in a first configuration, such that a camera of the electronic device faces a user facing a screen of the electronic display 228. For example, the fastener can be positioned such that a rear camera of the electronic device faces a user when the housing 200 is affixed to the electronic display 228. The fastener can be clip on the back of the housing as shown by FIG. 1 . In embodiments, the housing can have a folding element that rests the housing on top of the display 228.

A magnet is disposed within or attached to the housing 200. An example magnet 106 is shown by FIG. 1 . The magnet triggers a sensor 220 disposed within the electronic display. In embodiments, the sensor is disposed within a computer 208 communicably coupled to the electronic display. The sensor 220 can be a Hall effect sensor. A Hall effect sensor (or simply Hall sensor) is a type of sensor which detects the presence and magnitude of a magnetic field (e.g., generated by the magnet of the housing 200) using the Hall effect. The output voltage of a Hall sensor is directly proportional to the strength of the field. In embodiments, the magnet is a permanent magnet and the sensor 220 is a leaf sensor. The magnet can be a neodymium magnet. Advantageously, neodymium magnets have a smaller size.

The sensor 220 can cause the computer 208 to configure the mobile device to send data to the computer 208 in response to triggering of the sensor 220. For example, the data can be sent over the network connection 216, which can be any short range wireless network or universal serial bus (USB).

In embodiments, the computer 208 can be physically uncoupled but communicably coupled to the electronic display 228. In other embodiments as shown by FIG. 2 , the computer 208 is a laptop and the electronic display 228 is the screen of the laptop. For example, the laptop includes a display housing and a keyboard housing. The laptop includes sensor 220 in the display housing and a corresponding magnet in the keyboard housing. The sensor 220 detects an applied magnetic field by generating a voltage in response to the magnetic field as an electric current runs through the sensor 220, i.e., by the Hall effect. When the laptop is closed, the magnet in the keyboard housing is brought into proximity of the sensor 220, which triggers the sensor 220. The laptop can be configured, such as by software, to perform an action when the Hall effect sensor 220 is triggered. For example, the laptop's operating system can enter a sleep mode in response to triggering of the sensor 220.

In embodiments, the magnet in the housing 200 triggers the sensor 220 in the laptop when the housing 200 is attached to the display 228. The strength of the magnet can be chosen to trigger the sensor 220 when brought within a desired distance. For example, as shown in FIG. 2 , the magnet is adjacent to the sensor 220 in the display housing of the laptop, activating the sensor 220. Triggering the sensor 220 can cause the laptop to use the electronic device's camera as a webcam. In some embodiments, a laptop's sensor can be in a different portion, such as in the keyboard housing, or the laptop can have multiple sensors. The laptop can be configured to perform different actions depending on the placement of the triggered sensors, such as using the electronic device's camera as a webcam.

In embodiments, the sensor 220 causes the computer 208 to pair wirelessly with the mobile device in response to triggering of the sensor 220. For example, the sensor 220 can activate software on the computer 208 to run a software routine to cause the computer 208 to pair wirelessly with the mobile device. In another example, the computer 208 can include a circuit that uses a current or voltage generated by the sensor 220 as input. When the circuit senses the current or voltage generated by the sensor 220 in response to the sensor 220 being triggered by the magnet, the circuit causes the computer 208 to pair wirelessly with the mobile device. The pairing is a process that helps set up an initial linkage between the electronic device and the computer 208 to allow communications between them. For example, Bluetooth pairing can be used to link the electronic device and the computer 208. The laptop can be configured, such as by software, to cause the laptop to pair with the electronic device when a Hall effect sensor is triggered. This pairing can be via Bluetooth.

Once the laptop and electronic device are paired, the laptop's software can cause the laptop to expect or accept other communications signals from the electronic device, such as a Wi-Fi signal or a USB signal. These communication signals can include data such as a video stream captured by a camera of the electronic device, such as a rear camera or front camera. This allows the electronic device to function as a webcam.

In embodiments, the magnet is configured to cause the computer 208 to initiate the communication, such that the electronic device is configured to stream audio recorded by a microphone of the electronic device to the computer 208. For example, the communications signals can also include audio recorded by a microphone integrated into the electronic device.

The laptop is not limited to receiving video or audio streams being captured by the electronic device. In embodiments, video captured by a camera of the electronic device is first video. The magnet is configured to cause the computer 208 to initiate the communication, such that the electronic device is configured to send, to the computer 208, at least one of second video that mirrors a display of the electronic device, or files comprising at least one of images or documents. For example, the laptop can receive video that mirrors the electronic device's display. In another example, triggering the sensor 220 can cause the electronic device to transfer files to the laptop, such as photos or documents. In embodiments, the software or the circuit of the computer 208 causes the computer 208 to initiate communication between the electronic device and the computer 208 in response to the pairing. The electronic device is configured to stream images or video captured a camera of the electronic device to the computer 208. An example camera 108 is shown by FIG. 1 .

In some embodiments, the laptop can be configured to perform the described actions in response to other sensors 224 or a combination of sensors being triggered. For example, the laptop can be configured to use the electronic device's camera as a webcam in response to a change detected by an ambient light sensor 224 of the laptop. In this example, a user can attach the housing 200 to the laptop and cover the ambient light sensor 224, which then causes the laptop to use the electronic device's camera as a webcam.

FIG. 3 is a flow diagram illustrating an example process 300 for operating an electronic device as a web camera, in accordance with one or more embodiments. In some embodiments, the process 300 of FIG. 3 is performed by the computer 208. The computer 208 is illustrated and described in more detail with reference to FIG. 2 . In other embodiments, the process 300 of FIG. 3 is performed by a computer system, e.g., the example computer system 400 illustrated and described in more detail with reference to FIG. 4 . Particular entities, for example, software loaded within the computer 208, firmware of the computer 208, or a hardware circuit of the computer 208 perform some or all of the steps of the process 300 in other embodiments. Likewise, embodiments can include different and/or additional steps, or perform the steps in different orders.

In step 302, a sensor of the computer 208 detects a magnetic field emitted by a magnet disposed within or attached to a case housing a mobile device when the case is in proximity to the computer 208. An example magnet 106 and example case 100 are shown by FIG. 1 . The case includes at least one of rubber, plastic, leather, or silicone. An example sensor 220 is shown by FIG. 2 . For example, a magnetic field is detected. The magnetic field can be detected by a Hall effect sensor within a housing of an electronic display and emitted by a magnet in a case that houses the mobile device.

In step 304, in response to detecting the magnetic field, the computer 208 pairs wirelessly to the mobile device using a first network connection 212. The first network connection 212 is shown by FIG. 2 . For example, the mobile device is paired in response to detecting the magnetic field. This pairing can be via Bluetooth and initiated by software running on the computer 208.

In step 306, the computer 208 configures the mobile device to stream images or video captured by at least one camera of the mobile device to the computer 208 using a second network connection 216. The second network connection 216 is shown by FIG. 2 . For example, video data is received from the mobile device. The video data can be captured by a camera of the mobile device, so that the mobile device functions as a webcam. In embodiments, the computer 208 is a first computer. The first computer 208 initiates a video call with a second computer. The first computer 208 transmits images or the video stream to the second computer in the video call.

In embodiments, the second network connection 216 is the same as the first network connection 212. In embodiments, the first network connection 212 is Bluetooth and the second network connection 216 is Wi-Fi. In embodiments, the first network connection 212 is Bluetooth or Wi-Fi and the second network connection 216 is universal serial bus (USB). In embodiments, the computer 208 configures the mobile device to stream audio recorded by a microphone of the mobile device to the computer 208. In embodiments, the streaming video is first video. The computer 208 configures the mobile device to stream second video that mirrors a display of the mobile device to the computer 208. Configuring the mobile device to stream the images or video can be performed in response to detecting a change in light by an ambient light sensor 224 (see FIG. 2 ) of the computer 208

FIG. 4 is a block diagram illustrating an example computer system 400, in accordance with one or more embodiments. Components of the example computer system 400 can be used to implement a mobile device, the computer 208, etc. Likewise, embodiments of the system 400 can include different and/or additional components or can be connected in different ways. For example, the computer system 400 can be used to implement the mobile device of FIG. 1 that is placed in the case 100. The computer system 400 can include generic components and/or components specifically designed to carry out the disclosed technology. The computer system 400 may be a standalone device or part of a distributed system that spans networks, locations, machines, or combinations thereof. For example, components of the computer system 400 may be included in or coupled to a system-on-chip (SOC), a single-board computer (SBC) system, a desktop or laptop computer, a kiosk, a mainframe, a mesh of computer systems, or combinations thereof.

In some embodiments, the computer system 400 can operate as a server device or a client device in a client-server network environment, or as a peer machine in a peer-to-peer system. In some embodiments, the computer system 400 may perform one or more steps of the disclosed embodiments in real-time, near real-time, offline, by batch processing, or combinations thereof.

The computer system 400 includes a processing subsystem 402 that includes one or more processors 404 (e.g., Central Processing Units (CPUs), Application Specific Integrated Circuits (ASICs), and/or Field Programmable Gate Arrays (FPGAs)), a memory controller 406, memory 408 that can store software 410, and a peripherals interface 412. The memory 408 may include volatile memory (e.g., random-access memory (RAM)) and/or non-volatile memory (e.g., read-only memory (ROM)). The memory 408 can be local, remote, or distributed. The computer system 400 can also include a clock subsystem 414 that controls a timer for use in some embodiments. The components of the computer system 400 are interconnected over a bus (not shown) operable to transfer data between hardware components.

The peripherals interface 412 is coupled to one or more external ports 416, which can connect to an external power source, for example. The peripherals interface 412 is also coupled to an I/O subsystem 418. Other components coupled to the peripherals interface 412 include communications circuitry 420, audio circuitry 422 for a speaker 424 and a microphone 426, an accelerometer 428, a GPS receiver 430 (or Global Navigation Satellite System (GLONASS) or other global navigation system receiver), and other sensors (not shown). The GPS receiver 430 is operable to receive signals concerning the geographic location of the computer system 400. The accelerometer 428 can be operable to obtain information concerning the orientation (e.g., portrait or landscape) of computer system 400.

The I/O subsystem 418 includes a display controller 432 operative to control a touch-sensitive display system 434, which further includes the touch-sensitive display of the computer system 400.

The I/O subsystem 48 includes other components (not shown) to control physical buttons such a “home” button.

The communications circuitry 420 can configure the antenna 440 of the computer system 400. In some embodiments, the antenna 440 is structurally integrated with the computer system 400 (e.g., embedded in the housing 110 or display screen) or coupled to the computer system 400 through the external ports 416. The communications circuitry 420 can convert electrical signals to/from electromagnetic signals that are communicated by the antenna 440 to networks 442 or other devices. For example, the communications circuitry 420 can include radio frequency (RF) circuitry that processes RF signals communicated by the antenna 440.

The communications circuitry 420 can include circuitry for performing well-known functions such as an RF transceiver, one or more amplifiers, a tuner, oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM card or eSIM), and so forth. The communications circuitry 420 may communicate wirelessly via the antenna elements 440 with the networks 442 (e.g., the Internet, an intranet and/or a wireless network, such as a cellular network, a wireless local area network (LAN) and/or a metropolitan area network (MAN)) or other devices.

The software 410 can include an operating system (OS) software program, application software programs, and/or modules such as a communications module, a GPS module, and the like. For example, the GPS module can estimate the location of the computer system 400 based on the GPS signals received by the GPS receiver 430. The GPS module can provide this information to components of the computer system 400 for use in various applications (e.g., to provide location-based access to service providers).

A software program, when referred to as “implemented in a computer-readable storage medium,” includes computer-readable instructions stored in the memory (e.g., memory 408). A processor (e.g., processor 404) is “configured to execute a software program” when at least one value associated with the software program is stored in a register that is readable by the processor. In some embodiments, routines executed to implement the disclosed embodiments may be implemented as part of OS software (e.g., MICROSOFT WINDOWS and LINUX) or a specific software application, component, program, object, module, or sequence of instructions referred to as “computer programs.”

Computer programs typically comprise one or more instructions set at various times in various memory devices of a computing device (e.g., computer system 400), which, when read and executed by at least one processor (e.g., processor 404), will cause the computer system 400 to execute functions involving the disclosed embodiments. In some embodiments, a carrier containing the aforementioned computer program product is provided. The carrier is one of an electronic signal, an optical signal, a radio signal, or a non-transitory computer-readable storage medium (e.g., the memory 408).

Operation of a memory device (e.g., memory 408), such as a change in state from a binary one (1) to a binary zero (0) (or vice versa) may comprise a visually perceptible physical change or transformation. The transformation may comprise a physical transformation of an article to a different state or thing. For example, a change in state may involve accumulation and storage of charge or a release of stored charge. Likewise, a change of state may comprise a physical change or transformation in magnetic orientation or a physical change or transformation in molecular structure, such as a change from crystalline to amorphous or vice versa.

The computer system 400 can be any type of electronic device that can communicate wirelessly with a network node and/or with another handheld device in a cellular, computer, and/or mobile communications system. Examples of a handheld device include smartphones (e.g., APPLE IPHONE, SAMSUNG GALAXY, NOKIA LUMINA), tablet computers (e.g., APPLE IPAD, SAMSUNG NOTE, AMAZON FIRE, MICROSOFT SURFACE), wireless devices capable of machine-to-machine (M2M) communication, wearable electronic devices, and any other handheld device that is capable of accessing the networks 442.

The computer system 400 may store and transmit (e.g., internally and/or with other electronic devices over a network) code (composed of software instructions) and data using machine-readable media, such as non-transitory machine-readable media (e.g., machine-readable storage media such as magnetic disks, optical disks, read only memory (ROM), flash memory devices, and phase change memory) and transitory machine-readable transmission media (e.g., electrical, optical, acoustical, or other forms of propagated signals, such as carrier waves or infrared signals).

The computer system 400 can include hardware such as one or more processors coupled to one or more other components, such as non-transitory machine-readable media to store code and/or data, user input/output (I/O) devices (e.g., a keyboard, a touchscreen, and/or a display), and network connections (e.g., an antenna) to transmit code and/or data using propagating signals. The coupling of the processor(s) and other components is typically through one or more busses and bridges (also referred to as bus controllers).

FIG. 5 is a drawing illustrating an example of operating a mobile device 504 as a web camera, in accordance with one or more embodiments. The mobile device 504 can be mounted on top of a computer monitor 508. The computer monitor 508 does not have an integrated camera or webcam. The mobile device 504 sits on top of the monitor 508, e.g., using an adjustable clamp (e.g., the fastener 104 of FIG. 1 ) that braces itself against the back of the monitor 508 to secure the mobile device 504. Likewise, embodiments of the system 100 can include different and/or additional components or can be connected in different ways.

The housing 532 can include a fastener having a flexible base that can be used as a stand or as a clip to secure the mobile device 504 to the monitor 508. In embodiments, the fastener can be adjusted until a correct lens height of the mobile device 504 is achieved. In embodiments, the fastener is attached to the housing 532 and configured to attach the housing 532 to a frame of the monitor 508 in a first configuration (see FIG. 2 ), such that a first camera of the mobile device 504 faces a user facing a screen of the monitor 508. The fastener can enable the housing 532 to be rotated on the fastener into a second figuration (shown by FIG. 5 ), such that a second camera on the side 528 of the mobile device 504 faces the user.

In embodiments, the housing 532 attaches magnetically to a side of the mobile device 504. The housing 532 can have folds, dividing the housing 532 into portions, so it can be maneuvered to create a stand for the mobile device 504. The housing 532 can be used to prop the mobile device 504 up in an upright position for video calling. To expose a rear-facing HD video camera on the mobile device 504, the housing 532 can also be folded in half. The housing 532 aligns with the front screen of the mobile device 504 and is designed to add very little thickness to the overall profile of the mobile device 504.

A magnet is disposed within or attached to the housing 532. An example magnet 106 is shown by FIG. 1 . The magnet is configured to trigger a sensor 520 disposed within an electronic display (as shown by FIG. 5 ) or within a computer communicably coupled to the electronic display (monitor 508). The sensor 520 (triggered by the magnet) causes a computer to configure the mobile device 504 to send data to the computer in response to triggering of the sensor 520. For example, in response to detecting a magnetic field, the computer pairs wirelessly to the mobile device 504 using a first network connection. The computer configures the mobile device 504 to stream images or video captured by at least one camera of the mobile device 504 to the computer using a second network connection 516.

In embodiments, the sensor 520 is a reed switch operated by the applied magnetic field by the magnet. The sensor 520 can include a pair of ferromagnetic flexible metal contacts in a hermetically sealed glass envelope. The contacts are normally open, closing when a magnetic field is present, or they may be normally closed and open when a magnetic field is applied. The sensor 520 may be actuated by an electromagnetic coil in the housing 532, making a relay, or by bringing the magnet near it. When the magnetic field is removed, the contacts in the sensor 520 return to their original position.

The techniques introduced here can be implemented by programmable circuitry (e.g., one or more microprocessors), software and/or firmware, special-purpose hardwired (i.e., non-programmable) circuitry, or a combination of such forms. Special-purpose circuitry can be in the form of one or more application-specific integrated circuits (ASICs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), etc.
